Hello again -

So under the assumption my SoCKit h/w was broken, I bought a new board.
They are back ordered on SoCKit boards, so I got a DE0-Nano-SoC instead.

I build the v2016.03 (release) version of u-boot-with-spl.sfp.

I power-up the (brand new) board and get:

U-Boot SPL 2016.03 (Mar 15 2016 - 14:52:42)
drivers/ddr/altera/sequencer.c: Preparing to start memory calibration
drivers/ddr/altera/sequencer.c: CALIBRATION FAILED
drivers/ddr/altera/sequencer.c: Calibration complete
SDRAM calibration failed.
### ERROR ### Please RESET the board ###

=>

And this is a good case... usually it doesn't succeed after the fourth try
and I have to cycle power 4 or 5 times before I get lucky.

If I do get lucky and then try to see a USB storage device, then I get:

=>

(Every time)

The version of u-boot SPL that ships with the board:
U-Boot SPL 2013.01.01 (Dec 29 2014 - 15:29:15)

boots every time and has limited USB capability as
it can see some USB sticks, but not others.

Anyway - brand new board - same old symptoms.

Is it perhaps a toolchain problem?? I'm using:

Thread model: posix
gcc version 4.9.3 20141031 (prerelease) (Linaro GCC 4.9-2014.11)

< snip >

Any advice greatly appreciated.

Regards,
